MACHINE FOR MAKING CIGAR. ROLLS.

Application filed October 20, 1923, Serial No. 669,805, and in Sweden May 4, 1923.

his invention relates to a machine for manufacturing cigar rolls, and particularly to the separating from a string of tobacco of the filler adapted for a roll and to the removal of excess tobacco in making shaped cigars.

T he invention consists chiefly in this that the tobacco string having in known manner a thickness corresponding substantially to that of the roll to be produced is caught by a catching device and moved by said device to a cutting tool, which separates the tiller tobacco adapted for the roll, while the tobacco, which will in some cases on account of the shape of the roll be superfluous, is removed by means of the said cutting tool. To that last-mentioned end the cutting tool may, preferably, be provided with a sleeve or casing, through which the excess tobacco is led automatically during the cutting operation and from which the said tobacco may be easily removed.

In the annexed drawings one form of en'lbodinient of a machine according to the invention is shown. Fig. 1 shows the details for forming the roll tiller, viewed from above. Fig. 2 is a section along the line A-A and Fig. 3 a section along the line B-B of Fig. 1. Fig. 4 shows on an enlarged scale a front view of the cutting tool.

Figure 19 shows another detail.

estals 3, 4, Fig. 9, are displaceably arranged in vertical direction two slides 5 and 6, the slide 5 carries the cutting tool 10-14, Figs. 44', and obtains by a rod 16, Fig. 1, the desired reciprocating movement in any suitable manner, while the slide 6, Which 0btains the desired movement by means of a rod connection 19, carries a piston 18 adapted to move, after the roll filler has been cut oil, the said filler into a sleeve 20 secured to the machine frame 1 and having an interior form corresponding to the form of the piston 18 and of the cut off roll filler.

The cutting sleeve secured to the slide 5 consists of thin plates 10 and 11, the plate 1.0 of which is provided at the one side with an extension 12 bent along the whole length of the plate and at the other side with an extension 13 bent along part of the length. The said plates having cutting edges at the lower end are, as apparent from Fig. 5, riveted to plates 8 and 9 and will, when screwing together said plates, Figs. 4 and 7, be tightly pressed against each other having the extensions 12 and 13 resting on the plate 11, so as to form a sleeve open at both ends and widening in the direction from the bottom towards the top. By this the cutting sleeve will be considerably simpler and cheaper in manufacturing than a solid sleeve. Further, the plate 11 is provided with an extension 14, Figs. 4 and 6, forming that part of the cutting tool, by which the roll filler will be cut off from the string.

The filler leaves forming the string are placed on a conveyer device mounted on the machine frame 1, said conveyer device consisting, for one thing, of an endless band running over a driving roller 39 and guide rollers and, for the other, of two endless bands 44 running over rollers 42 and 43, said latter bands forming, as apparent from Fig. 12, together with the band 40 a movable conveyor channel. The band On the machine frame 1 resting on ped- 40 obtains its movement from the driving roller 39, on the shaft 38 on which a ratchet wheel is secured cooperating with a pawl 34 pivotally connected to a double-armed lever 31, 82 swingable about the shaft 38, said lever obtaining in a suitable manner a swinging movement by means of a rod con nection 03. The shafts 49 of the rollers 42 driving the bands 44. are connected by means of bevel gears 48 with the driving shaft 38 and will thus be driven simultaneously with said shaft, the transmission ratio and the size of the rollers 89 and 12 being so chosen that the bands 40 and 14 will obtain the same speed.

The tobacco string thus .ted is grasped, when leaving the conveyer bands 1 1, by a catching device consisting of two gripping members 21 having the form of plates or lists and being pivotally connected at 17 with a slide '7 movable on the machine frame 1, the free ends of said catching member being irovided with bands 37 secured to and running about rollers 36 pivotally mounted on the machine frame. The said rollers 36 tend to turn through the action of springs or the like so that the bands 37 will always be held stretched. The gripping members 21 are actuated by a spring a'l, Figs. 9, 11 13--15, which tends to force the said members to the separated position shown in urc 15. Crank levers 23, 25 are pivotally mounted on the frame, and the arms 25 of said levers interengage by means 01 teeth the arm 23 of one lever receiving movement at proper times from a rod connection 26, which movement is transmitted by means of the teeth to the other lever so that the gripping members 21 will be moved together against the action of the spring 1-1 to the position shown in l igures 1e. and 15. he slide 7 carrying the gripping members 21 is provided with a rack 16 cooperating with a toothed segment formed on the one arm 28 of the lever, which is rotatably mounted in the trame by means of a pivot 29 and the other arm 30 of which is connected by a link rod 27 with the one arm 31 of a driving lever 23., 32. The arm 31 is pivotally conruscted to a pawl 34. while the other arm 32 is pivotally connected to the rod 33, vhich obtains a reciprocating movement from the main shaft 100. The rod is pivotally connected with the lower end of the arm .120 and carries a roller 119 engaging a cam race in the cam disk 117 on the shaft 100. while the upper end of the arm 120 is swingable on the stud 121. In swinging the said arm 31, 32 counter-clockwise, i. e., when the pawl 34 moves over the teeth of the ratchet wheel 35 the slide 7 with the gripping members 21 will thus be moved by means oi the rod .47, the arm 30 with the toothed se ment 28 and the teeth 46 in the direction towards the tobacco string fed tor-wards by the conveyor bands 40, 44, while, when turning the arm 31, 32 in opposite direction the slide 7 vith the gripping members 21 will be moved in the direction from the conveyer bands 44, which will simultaneously continue to move together with the band at). In this case the length the arms 30 and 31 ought to be so chosen that the gripping members 21 will obtain the same speed as that of the conveycr bands -10. 41ft, i. e. of the tobacco string fed forwards by said bands, thus preventing stretching or compressing, respectively, of the said string. lly forming the gripping members 21 as plates or extensions and by providing said members at the free end with bands 37 having prererably the same height as have the gripping members and being stretched by the spring-actuated rollers 30, the tobacco string will have a reliable guid ance, even att-er having left the coi'iveyer bands 44-. Each roller 36 loosely mounted on its shaft 122 and the coil spring surrounding the shaft 122 has one end secured to the roller 36 and its other end secured to the plate 124, which is secured to the shaft 122. i lrrano' close to and on a level with the coin U 1 bands 10 a cutting plate 22 serving besides, as a stripper and which. as apparent from 10 c:-;- tends onto a sleeve 20 secured to the machine frame. said plate covering partly the material in the one wall of the sleeve but leaving the wnole opening tree.

The filler tobacco adapted for the rolls to be produced is, as mentione-rh introduced into the channel term-ed by the conveyor bands and let and the said bands are put in an intermittent motion by the driving device 33, 34:, 35. The tobacco string is ted torwards and caught by the gripping members 21 by which it will be moved over the cut ting plate 22 to the cutting tool 10-41- loated above said plate at the side of the sleeve 20. At this time the feeding motion of the tobacco string ceases and the slide 53 with the cutting tool 101'l is moved downvards and cuts oil a portion 15 from the string, Fig. 8, and simultaneously separates. by means of the extension l-fl, the roll from the string 51 along the line 16. As apparent troin Fig. 8. the fore end or" the string 51 obtains thus a form correspoinling to the top end of the roll 50 simultaneously cut ofl. The said roll 50 obtains the same term as that 01? the opening in the sleeve 20 into which it is now moved. down by the action of the piston 1.8 and from which it will be automatically removed for further treatment in known manner. The slides 5 and 6 with the cutting tool 1O1 1- and the piston 18 are then moved upwards and simultaneously the gripping members 21 are moved on the arm 31 32 in the direction towards the conveyer band 10, 4/1, the arms 23 being also actuated so that the gripping members separate by the action 01 the spring 41. After the gripping members 21 having reached their toremost position. thev are again actuated by the arms 23 and will a 'ain erase the tobacco string the de- .l: p L in ill) lift) scribed process being then repeated. The conveyer channel formed by the bands 410, a l may continuously be held packed with filler tobacco so that the manufacturing of the rolls may proceed continuously. The portions 15 cut off by the cutting sleeve 10 13 are automatically moved upwards through the sleeve from which they drop into an adjacent channel 17 and are removed.

Obviously the sleeve 20 adapted to receive the roll need not, shown in the drawing, be arranged immediately below the cutting tool, as it is preferably displaced relatively to the cutting tool in the direction of feeding of the gripping members so that the introduction of th roll into said sleeve 20 will be performed after the said roll has been moved a step further in the feeding direction by the gri iiping members. Thus, according to this n'ioditication while a roll blank is cut off from the rope the roll blank cut off by the preceding action occupics at position between the gripping members, which lies nearer the pivot 17. In such a case the gripper membcrs at those parts which seize the preceding roll blank, and which of course, in their front position lie opposite the sleeve, will have. a form corresponding to the roll blank so that the raid roll may not be injured or deformed before being moved down into the sleeve 20 by the piston 18. i

The said rod 19, through which the piston 18 is driven, obtains its i'i'iovement from a rotating main shaft 100 by the following device, Figs. 16, 17.

The shaft 100 is provided with a cam disk 1.01 which cooperates with a roller 103 carried by a fork 102 grasping over square piece 113 on the shaft 100, and the stem 104- of which is pivotally connected with the arm 105, which at its one end is pivoted to the fame part 106, while the other end thereof is pivotally connected to the rod 19.

The rod 16, through the reciprocating movement of which the cutting tool is moved, obtains its movement, Figs. 16, 17 from a cam disk 107 on the main shaft 100, the disk cooperating with a roller 108, which is ournaled in a. fork 109, which grasps over a square piece 113 on the shaft 100, and the stem of which is pivotally connected with an arm 111, which with its one end is pivoted to the frame part 106 and with its other end to the said rod 16.

The rod 26, through the movement of which the gripping members are opened, obtains its movement from the cam disk 112 on the main shaft 100, said disk cooperating with a roller 11-1, which is journaled in a vertical arm 115 swingably mounted with its lower end in a stud 116, secured to the frame part 3, while the upper end of arm 115 is pivotally connected to the said rod 26.
